"Ghost in the machine" is a series of images created by Flickr user iri5. The artist, who specialises in non-traditional media, uses " old books, cassettes, playing cards, magazines, credit cards... whatever I can find."

"It feels great to work with strange, older materials," iri5 says. "Things that have a mind of their own. Most everything I use has been thrown away or donated at some point. Past its prime, like some of the finest things in the world."
